Ordnermigration von einem Windows-PC auf einen anderen mithilfe eines Python-Skripts ⇐ Python

[Anonymous]

Ich möchte eine Ordnerbaumstruktur von einem Windows-PC auf einen anderen migrieren, indem ich ein Python-Skript auf dem Ziel-PC ausführe. Hier ist der Code, den ich verwende:

Code: Select all

import shutil
import os
import sys
import logging
import subprocess
from datetime import datetime
from pathlib import Path

# =======================
# CONFIGURATION
# =======================

# UNC root of source machine (example: r"\\OLD-PC\C$")
# SOURCE_ROOT = r"D$
SOURCE_ROOT = Path("D:\\")

# Local destination root (almost always C:\)
# DEST_ROOT = r"C:\\"
DEST_ROOT = Path("C:\\")

# Folders to migrate (absolute paths from source C:\)
FOLDERS_TO_MIGRATE = [
r"dgarrard",
r"PNC",
r"Installers",
r"Nufocus",
r"openssl",
r"win-acme",
r"ProgramData\win-acme",
r"Program Files\Inkscape",
r"MYPROGRAMS\wkhtmltopdf"
]

# Log file
LOG_FILE = rf"C:\migration_log_{datetime.now().strftime('%Y%m%d_%H%M%S')}.log"

# =======================
# LOGGING SETUP
# =======================

logging.basicConfig(
level=logging.INFO,
format="%(asctime)s [%(levelname)s] %(message)s",
handlers=[
logging.FileHandler(LOG_FILE, encoding="utf-8"),
logging.StreamHandler(sys.stdout)
]
)

# =======================
# FUNCTIONS
# =======================

def ensure_admin():
import ctypes
if not ctypes.windll.shell32.IsUserAnAdmin():
print("❌ This script must be run as Administrator")
sys.exit(1)

def safe_copytree(src, dst):
"""
Copy directory tree while:
- Preserving metadata
- Skipping reparse points
- Copying only newer files
"""
for root, dirs, files in os.walk(src):
# Skip reparse points (junctions, symlinks)
if os.path.islink(root):
logging.warning(f"Skipping symlink: {root}")
continue

rel_path = os.path.relpath(root, src)
dest_dir = os.path.join(dst, rel_path)

os.makedirs(dest_dir, exist_ok=True)

for file in files:
src_file = os.path.join(root, file)
dst_file = os.path.join(dest_dir, file)

try:
if not os.path.exists(dst_file) or (
os.path.getmtime(src_file) > os.path.getmtime(dst_file)
):
shutil.copy2(src_file, dst_file)
logging.info(f"Copied: {src_file} -> {dst_file}")
else:
logging.info(f"Skipped (up-to-date): {dst_file}")
except Exception as e:
logging.error(f"Failed copying {src_file}: {e}")

def migrate_folder(folder_relative_path):
src_path = os.path.join(SOURCE_ROOT, folder_relative_path)
dst_path = os.path.join(DEST_ROOT, folder_relative_path)

if not os.path.exists(src_path):
logging.error(f"Source not found: {src_path}")
return

logging.info(f"Starting migration: {src_path} ->  {dst_path}")
safe_copytree(src_path, dst_path)
logging.info(f"Completed migration: {folder_relative_path}")

# =======================
# MAIN
# =======================

def main():
ensure_admin()
logging.info("==== Folder Migration Started ====")

for folder in FOLDERS_TO_MIGRATE:
migrate_folder(folder)

logging.info("==== Folder Migration Completed ====")
logging.info(f"Log file saved to: {LOG_FILE}")

if __name__ == "__main__":
if not os.name == "nt":
logging.error("This script is intended for Windows only.")
sys.exit(1)

main()

Wenn ich dies mit IDLE auf dem Ziel-PC ausführe (IDLE als Administrator ausführen), erhalte ich die folgende Protokolldateiausgabe:

Code: Select all

Der Quell-PC ist im Netzwerk verfügbar und kann im Windows-Dateibrowser auf dem Ziel-PC angezeigt werden, sodass ich nicht verstehe, was ich falsch mache. Es scheint, dass es mit meiner Definition von Volumes und/oder Ordnern zusammenhängt.
Vielen Dank
